Question

fill ups: if the speed of moving object is increased to 3 times of its initial value , then its kinetic energy rises to____________of its initial value.. ​

Answer 1

Answer:

Nine times or factore of nine

Explanation:

KE = 1/2 x m x v^2

Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed)

If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
